Zebco ASTM Flanged End Stainless Steel ball valves, Color : Silver

A ball valve is a valve that opens by turning a handle, gearbox or other actuation methods attached to a ball inside the valve. The ball has a hole, or port, through the middle so that when the port is in line with both ends of the valve, flow will occur. When the valve is closed, the hole is perpendicular to the ends of the valve, and flow is blocked. The handle or lever will be in line with the port position letting you "see" the valve's position, position indicators will be applied to gearbox or actuators when required. Ball valves are durable and usually work to achieve perfect shutoff even after years of disuse. They are therefore an excellent choice for shutoff applications. There are two type of ball valve based on the ball type, floating ball valve and trunnion mounted ball valve. Depends on the bore size, ball valve is separated into full port ball valve and reduced port ball valve. There are three types of body styles of ball valve: one-piece, two piece split, three piece split, top entry and welded, GVC ball valves are available in two piece split, three piece split and welded.

Advantages of using Ball Valves:

• Quick quarter turn on-off operation

• Tight sealing with low torque

• Smaller in size than most other Valves }

Types of Ball Valves

Ball Valves are basically available in three versions: full port, venturi port and reduced port. The full-port Valve has an internal diameter equal to the inner diameter of the pipe. Venturi and reduced-port versions generally are one pipe size smaller than the line size.

Ball Valves are manufactured in different body configurations and the most common are:

• Top entry Ball Valves allow access to Valve internals for maintenance by removal of the Valve Bonnet-cover. It is not required to be removed Valve from the pipe system.

• Split body Ball Valves consists of a two parts, where one part is smaller as the other. The ball is inserted in the larger body part, and the smaller body part is assembled by a bolted connection.

The Valve ends are available as butt welding, socket welding, flanged, threaded and others.
